Spiking Neural Processor Pulsar
The world's first neuromorphic microcontroller for the sensor edge
Pulsar is the first neuromorphic microcontroller built for real-time intelligence at the sensor edge. Delivering brain-like efficiency in a milliwatt power envelope, it enables always-on, responsive devices across wearables, IoT, and industrial systems.

Where our technology makes a difference
Always-on intelligence without draining battery
Pulsar delivers real-time, event-driven intelligence directly at the sensor, enabling sub-millisecond response at microwatt power. Always-on, high-performance inference means no trade-off between accuracy and energy use. Application processors stay asleep until needed, extending battery life for human detection, gesture recognition, and environmental sensing; all without cloud dependence.
Smarter sensors for the edge
Embed intelligence directly into sensors. Pulsar combines SNN and DNN inference with an integrated CPU in a single chip, reducing system cost and complexity. Ultra-low energy use, short latency, and a compact 2.8 × 2.6 mm footprint enable faster development cycles and scalable deployment across edge applications.
